| Application: | 4-Hydroxyphenylboronic acid can be used as a reactant in: • Suzuki-Miyaura coupling and Stille coupling reactions. • Palladium-catalyzed aminocarbonylation and cross-coupling reactions. • Suzuki reaction for preparation of bio-supported palladium nanoparticles as phosphine-free catalysts. • Cu2O-catalyzed aerobic oxidative cross-coupling of tetrazoles. It can also be used to prepare/promote: • PDK1 inhibitory activity (cancer cell growth, survival, and tumorigenesis inhibitor). • Rod-like dendronized polymers containing G4 and G5 ester dendrons via macromonomer approach by living ROMP. • Estrone-derived cyclopamine analogs as Sonic Hedgehog signaling inhibitors for anti-cancer chemotherapeutics. • Enzymatic inhibitors for the treatment of Gram-negative bacterial infections. • Oligoarenes by Suzuki-Miyaura palladium-catalyzed cross-coupling. |
